“Aumonier entered the Paris Conservatory as a pupil of Léon Melchissédec. Most of his career was spent on the stages of provincial theaters including Monte Carlo, Lausanne, Brussels, Algiers, Nice, and Rouen. He appeared with van Dyck, Albers, Demougeot, and Caruso. Aumonier took part in the premiere of Edouard Trémisot’s PYRAME ET THISBÉ (Monte Carlo, 1904), Mazellier’s GRAZIELLA (Andréa, Theatre des Arts in Rouen, 1913), and Trémisot’s STAMBOUL (Mehmed Pacha, Algiers Opera, 1924). He also sang at the Paris Opéra in SAMSON ET DALILA, SALAMMBÔ, AÏDA, ROMÉO ET JULIETTE, AND RIGOLETTO. Aumonier, who recorded extensively for all of the French record labels, possessed one of the most beautiful basso profondo voices of his time."
